Acute CPP crystal arthritis

Calcium crystal diseases

Acute CPP crystal arthritis (also known as pseudogout) is a type of calcium crystal disease. It occurs when calcium pyrophosphate (CPP) crystals deposit within the joints, which can cause sudden attacks of painful inflammation. Symptoms of acute CPP crystal arthritis include:

  • sudden pain and stiffness in affected joint (most commonly knee)
  • swelling and tenderness
  • red, inflamed skin over the joint
  • raised temperature
  • generally feeling unwell.

Treatment for acute CPP crystal arthritis can include a range of drugs, joint aspiration and injection, and lavage.

You can find more information about acute CPP crystal arthritis on our calcium crystal diseases pages.
